Freelancer Availability Tool, Vrend

I'm working on a tool primarily to serve a purpose within Sixo.co. We want to be able to know when freelancers are available for work, and Vrend is the first step. It'll later become a small part of a suite of tools

Vrend will allow people to see who in their network (i.e. Twitter) is free for work, either immediately or months into the future. It eliminates the need to blindly ask about availability and easily find the best person from within your existing network.

Public profiles will also highlight availability, and we're hoping to have an API ready which will allow people to hook into their data and display it on their own website.

Let me know what you think!
